ADS Race Multi-Bypass Ring (MBR) Coilover Piggyback Reservoir - 300-MBP16-000MBR technology, or Multi Stage Bypass Ring, embodies a genuine multi stage bypass system where each zone is independently adjustable via a positive stop helix system. This design ensures ample flow, similar to 7 tube External bypasses on 16" stroke variations, and internal free bleed ports enable tuners to optimize the damping curve for specific vehicle needs. A true top out zone provides both mechanical and hydraulic damping, guarding against shock
